[PD] Pd - DSP in a web app

Well, the question is how the audio is getting to the user.  As you said, WebPd requires FF4's audio API.  If you want the actual Pd running on a server then you need a way of hearing the output.  In my own pd-on-the-web project, PuréeData, I'll be using an mp3 or ogg stream.  Latency will be an issue, but hopefully not a tremendously bad one.
